Detailed implementation manners

[0023] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0024] An air filter with a cross beam strengthening structure, as Figures 1 to 5 shown, includes an upper housing 1 and a lower housing 2, and the upper housing 1 and the lower housing 2 are detachably connected. In this embodiment, the upper housing 1 and the lower housing 2 are connected by a plurality of screws.

[0025] The lower housing 2 is provided with an air inlet end 3, and the upper housing 1 is provided with an air outlet end 4. The air inlet end 3 and the air outlet end 4 are communicated. Specifically, a first cavity 17 and a second cavity 18 are provided in the lower housing 2. The second cavity 18 is located outside the first cavity 17. The first cavity 17 is communicated with the air inlet end 3, and the first cavity 17 is communicated with the second cavity 18. The upper housing 1 is provided with a third cavity 19 and a fourth cavity 20. The fourth cavity 20 is located outside the third cavity 19. The first cavity 17 is communicated with the third cavity 19, and the fourth cavity 20 is communicated with the second cavity 18. The third cavity 19 is communicated with the air outlet end 4, and the second cavity 18 and the fourth cavity 20 increase the air flow space, can effectively disperse the air flow, thereby adjusting the air flow speed and pressure, and thus realizing the noise reduction of the air flow.

[0026] A filter element 5 is arranged inside the lower housing 2, and a sealing gasket 6 is arranged between the upper housing 1 and the lower housing 2. When the air flow passes through the filter element 5, the filter element 5 filters it, and the sealing gasket 6 effectively seals between the upper housing 1 and the lower housing 2 to ensure the sealing performance between the two.

[0027] An installation groove 15 is arranged at the end of the lower housing 2, and the sealing gasket 6 is arranged in the installation groove 15. The position of the sealing gasket 6 is restricted by the installation groove 15, thereby ensuring the stability of the sealing gasket 6 and facilitating the installation of the sealing gasket 6.

[0028] Anti-slip strips 16 are arranged at the bottom of the installation groove 15, and the anti-slip strips 16 are in contact with the lower surface of the sealing gasket 6. The sealing gasket 6 is made of a high-elastic material. The upper housing 1 presses the sealing gasket 6 in the installation groove 15. It should be noted that since the sealing gasket 6 is made of a high-elastic material, the sealing gasket 6 can deform when subjected to pressure. When the upper housing 1 presses the sealing gasket 6 in the installation groove 15, the pressure acts on the sealing gasket 6, and the anti-slip strips 16 are embedded in the sealing gasket 6, thereby realizing the effective limit of the anti-slip strips 16 on the sealing gasket 6, further ensuring the stability of the sealing gasket 6 and preventing the sealing gasket 6 from shifting.

[0029] A support cross beam 7 is arranged inside the lower housing 2. The two ends of the support cross beam 7 are respectively connected to the inner side walls on both sides of the lower housing 2. In this embodiment, the support cross beam 7 is integrally arranged with the lower housing 2 to ensure the structural strength.

[0030] The structural strength of the lower housing 2 and the strength of its internal support structure can be effectively improved through the support cross beam 7. When the housing is subjected to external forces, the forces can be transmitted to the support cross beam 7, and the support cross beam 7 resists deformation and damage through its support. When the lower housing 2 is subjected to external impacts or internal pressures, the support cross beam 7 can effectively disperse and absorb these forces, thereby protecting the lower housing 2 from damage or reducing the degree of damage.

[0031] A plurality of strip-shaped grooves 14 are formed on the upper surface of the support cross beam 7. The strip-shaped grooves 14 are formed along the length direction of the support cross beam 7 to reduce the consumption of materials and reduce the weight.

[0032] Support protrusions 8 are arranged on the inner side walls on both sides of the lower housing 2. The side walls of the lower housing 2 are recessed inward to form the support protrusions 8, which can effectively improve the overall structural strength of the lower housing 2, and there is no need to add additional materials to set the support protrusions 8, which helps to save material costs and reduce the overall weight.

[0033] The two ends of the support cross beam 7 are respectively fixedly connected to the upper ends of the two support protrusions 8, and the support cross beam 7 is effectively supported by the two support protrusions 8 to ensure the stability of the support cross beam 7.

[0034] On the outer side wall of the upper shell 1, several first reinforcing rib blocks 9 are provided, and on the inner side wall of the upper shell 1, several first reinforcing rib strips 10 are provided, thereby effectively improving the structural strength of the upper shell 1 and the anti-deformation ability of the upper shell 1.

[0035] On the outer side wall of the lower shell 2, a second reinforcing rib block 11 is provided, and on the inner side wall of the lower shell 2, several third reinforcing rib blocks 12 and several second reinforcing rib strips 13 are provided, thereby effectively improving the structural strength of the lower shell 2 and the anti-deformation ability of the lower shell 2.

[0036] An intake pipe 21 is sleeved on the intake end 3, a clamping protrusion 23 is provided on the intake end 3, a clamping hole 22 is formed in the intake pipe 21, and the clamping protrusion 23 can be clamped in the clamping hole 22. Through the cooperation and clamping of the clamping protrusion 23 and the clamping hole 22, the detachable connection of the intake pipe 21 is realized, which is convenient for disassembly and maintenance.

[0037] An outlet pipe 24 is sleeved on the outlet end 4, a positioning protrusion 25 is provided on the outlet end 4, a clamping groove 26 is provided on the inner side wall of the outlet pipe 24, and the positioning protrusion 25 can be clamped in the clamping groove 26. Through the cooperation and clamping of the positioning protrusion 25 and the clamping groove 26, the detachable connection of the outlet pipe 24 is realized, which is convenient for disassembly and maintenance.

[0038] A limiting protrusion 27 is provided at the end of the outlet pipe 24, a limiting groove 28 is formed in the outlet end 4, the limiting protrusion 27 is adapted to the limiting groove 28, and the limiting protrusion 27 is inserted into the limiting groove 28.
